Insane

A Sufi mosque in Egypt, on the Sinai Peninsula on the Mediterranean, was subject to a horrific terrorist attack. 235 people are reported dead so far. 235, including 15 to 25 children. My gosh, just pray for them. It's absolutely horrific. I've written before that Sufism is usually considered a mystical form of Islam, but many Muslims (perhaps most) consider it heretical. I presume that would be the motive here, but the larger part of me isn't interested in the motives of evil people for committing evil but on asking how we stop them.
